TYPE-WRITING MACHINE.

SEPECIFICAIION forming part of Letters Patent No. 620,774, dated March'7, 1899.

Application filed August 19, 1898. Serial No. 688,981. (No model.)

To to whom, it may concern:

Be it known that we, EDWARD B. HESs,0f the city and county of New York,and JOSEPH M. STOUGHTON, of the city of Yonkers and county of\Vestchester, State of New York, citizens of the United States ofAmerica, have invented certain new and usefullmprovements in Type-I'Vriting Machines, of which the following is a specification.

This invention relates to that class of typewriting machines in whichpivoted type-bars are each provided with a plurality of type orcharacters arranged longitudinally thereon and each bar operated uponthrough the medium of a plurality of finger-keys, one for eachcharacter, and one or more of which impart to the type-bar a motionaround its pivot and longitudinally or in the direction of its length tobring the desired character to the point of printing or impact upon theplaten. Machines of this general class are shown in the patents toBurridge, Nos. 585,838, 593,563, andv 59%,777. A machine more intimatelyallied in details of construction to that herein described is also shownin a patent to us, No. 610,400, dated September 6, 1898, and upon whichthe invention of the present specification is in its main features moreparticularly an improvement.

In the machine herein described, as in that of the above application,each type-bar is equipped with a sleeve having three type-carryingfaces, upon each of which a series of type is arranged longitudinally,three type being shown upon each such face. Each typecarrying sleeve maybe partially rotated at will to bring the type or characters upon eitherof its three surfaces opposite the platen in proper position to printwhen the lever is operated. Three keys are shown for each lever, andeach key when depressed brings to the printing-point the correspondingcharacter upon that face of the type-carrying sleeve then opposite theplaten.

The invention consists, primarily, in two features-first, theorganization by which a type-lever is actuated to bring either of threecharacters then opposite the platen to the printing-point upon theplaten, and, second, the organization relating to the partial rotationof the sleeve or part of the type-bar having thereon the type orcharacters to' be printed.

The organization by which the three keys of each type-lever effect thethree phases of movement of that lever is not dependent upon theorganization relating to the partial rotation of the type-carryingsleeves or parts, nor is the latter organization dependent upon theformer. The key mechanism may be used with a different organization forbringing different series of type or characters opposite the platen, andthe latter mechanism may be employed in machines having a different keymechanism from that herein shown.

In the accompanying drawings, Figure 1 is a vertical section at rightangles to the cylindrical platen; Fig. 2, asimilarsectionlooking in theopposite direction and showing the key mechanism for operating one ofthe typebars; Fig. 3, a similar section taken at the side of themachine, showing the shifting keys and mechanism for efiecting a partialrotation of the type-carrying sleeves; and Fig. 4,a view of the samemechanism at right angles to Fig. 3. Figs. 5 and 6 are respectivelydetail views of pivoted slotted plates operated by the shifting-keys toaccomplish the partial rotation of the type-carrying parts or sleeves;Fig. 7, a plan view of a part of the machine, showing the type carryingsleeves and a means for effecting their partial rotation. Fig. 8 is arear view of the same parts, showing also the device for guiding thetype-bars to bring their type-carrying sleeves into gear with theshifting-rack and the locking-comb for holding the typebars while thetype-carrying sleeves are being shifted or partially rotated. Fig. 9 isa bottom view showing more particularly the latter device. Figs. 1O, 11,and 12 are detail views showing the type-carrying sleeves andlocking-latches to secure them in either position to which they may beshifted or partially rotated. Figs. 13, 14, 15, and 16 are detail viewsshowing modifications of the locking-latches of the sleeves; Fig. 17, asection with some of the parts removed on the line 17 17 of Fig. 1.

For each type-bar there is a vertical plate 1, pivoted at its lower endin the bed-plate and having in its enlarged or widened upper described.For each such plate there are three finger-keys 5 6 7, and the keys 5 .7carry laterally-projecting lugs or studs 5 7 which when the keys andother parts are in their normal inactive positions, as shown in Figs. 1and 2, occupy the ends of the slot 2. The lugs 5'7 act as stops to limitthe rise of the keys 5 7 and also when both these keys are inactive asstops to prevent motion of the plate 1 about its pivot. The central key6 may have a cross-pin 6 engaging the under face of the top plate tolimit its upward movement. The keys may be constructed in any desiredmanner. As shown, each has at its lower end a lateral projection with anaperture through which passes a vertical pin 8, fixed in the bed-plate,a coiled spring 9, surrounding the pin, being interposed between thelateral projection of the key and the bedplate.

Each type-bar 10 may be constructed in any suitable manner of one ormore pieces and is pivoted at 10 in the rear end of a horizontal bar orplate 11, pivoted at 11 on the plate 1 and pivotally connected at itsfront end to a vertical bar 12, rocking upon a pivot 12 in thebed-plate. At a suitable point between the pivots 11 12 a horizontal bar13 is pivoted to the bar 12, and at or near its rear end the bar 13 isconnected by a swiveling link 14L with a projection on the type-baradjacent to its pivot. The rear end of bar 13is guided in a verticalslotted guideplate 15, and the front end of the bar 11 has anupwardly-extendin g projection similarly guided in a slot in ahorizontal plate 15. Preferably the horizontal bar 11 is formed with ahook 16 at its upper edge, the vertical part of which extends across theslot 2 and the horizontal part above the lug or stud 5. The upper edgeof the hook works in a slot in a transverse slotted rod 17. In these orany other suitable ways the mechanism may be guided and braced againstlateral strains. Each key near its lower end has a foot or projection18, extending above a pin or stud 19, projecting laterally from the bar13, and the bar 13 extends over the transverse bar 20, which is theuniversal bar of the machine, and controls the carriage and ribbon feed,as hereinafter described.

As is well understood, each type-bar 10, except the middle one, isangularly displaced or bent with reference to a horizontal plane tobring the letters or characters thereon to the proper printing-point onthe platen. Also the axis of the pivot 10 of each type-bar is at suchangle to the axis of the platen-roller as to cause the characters on thetype-bars to properly converge on the printing-point when the bars areactuated to take an impression. This may be conveniently accomplished bydeflecting the rear ends (those nearest the platen) of the bars 11 oneach side of the central one to which the central type-bar is pivoted.This is well understood and is shown in Figs. 1 and 17. On thedepression of the center key 6 its foot 18, acting upon the pin 19,carries down the bar 13 and the type-bar 10 is thrown to bring themiddle type or character Z) to the printing-point on the platen. Theparts are returned to normal position by the springs 9 and 13, and nospecial device is required during the movement of the key to hold theplate 1 stationary, the lugs 5'7 performing this function. If the key 7be depressed, the same operation occurs, with the addition that alongitudinal movement of the type-bar toward the rear of the machineoccurs, so that the letter or character marked 0 is brought to theprinting-point. This operation is efiected by the lug 7 passing down theinclined slot 4 in the plate 1, thus rocking the plate 1 upon its pivotand carrying it toward the rear of the machine until the lug enters thereversely-inclined bottom part of the slot, which, however, now standsvertically with the plate in the angular position into which it has beenrocked. The movement of the plate therefore ceases, and the continueddescent of the key produces the impact of the type upon the platen.During this operation the slot 2 permits the free move ment of the plate1 relatively to the lug 5 on the key 5. lVhen the key 5 is depressed,precisely the same operation occurs, except that the lug 5 now moves theplate 1 toward the front of the machine, thus imparting a longitudinalmovement to the type-bar in the reverse direction, thus bringing thecharacter which is arbitrarily marked a to the printingpoint on theplaten. This organization possesses several advantages, among which maybe mentioned the positive holding of the plate 1 in its normal positionand when the center key is depressed by the devices which cause itsoperation when the other two keys are depressed, thus giving rigidityand stability to the parts without the employment of any specialmechanism for that purpose.

The mechanism relating to the partial rotation of the type-sleeves orparts of the typebars will now be described.

Each type-bar carries at its outer end a rotatable sleeve 21, mountedthereon in any suitable manner and having three faces marked A B 0, eachof which carries three characters, longitudinally arranged andarbitrarily marked a b c. The back of each sleeve is formed withgear-teeth 22, adapted to mesh when the type-bars are in the normalelevated engagement with the notched plate 25.

position with the teeth of an endwise-movable rack A pivoted latch 24:is adapted to engage with either of three notches in a plate 25, securedto the end of the sleeve, and has a prolonged end 26, on which bears aspring 27, that tends normally to throw the latch into The rack 23 iscurved and is mounted, through the medium of slots and set-screws 23 orin any suitable manner, upon a bracket or part 29 of the frame, alsopreferably curved. Below the rack is mounted a slotted type-bar-guidin gplate 30. This plate is preferably curved reversely to the rack 23 andhas a series of slots, one for each type-bar, which are flared orwidened at their outer ends and closely fit the type-bars at their innerends, so that as a type-bar rises it is sure to enter its slot and beaccurately guided to bring the gear-teeth thereon into operativeengagement with the teeth upon the rack 23. The guide-plate 30 is fixedat 31 .upon the bracket or part 29 of the frame.

It will be obvious that if the center typebearing faces A of thetype-bearing sleeves are opposite or facing the platen they may all bepartially rotated in either direction (provision being made foroperating the latches if employed) by the movement of the rack, so as tobring either the type-bearing faces B or O opposite the platen. Eithertype-bearing face of any type-bar being thus brought opposite the plateneither character thereon arbitrarily marked a b 0 may be brought to theprinting-point at will by the manipulation of the keys 5, 6 or 7. Thisgeneral operation is disclosed in our application above referred to, andthe present invention relates to improved means for operating the rack,means for locking the type-bars while the sleeves are being partiallyrotated, and means for releasing the sleeves to permit of their partialrotation and locking them in either of their three positions. Thelocking of the type-bars may be accomplished in a variety of wayswithout departing from the principles of this invention. The specificform in which this part of the invention is embodied consists in alocking-comb 33, having curved or hooked teeth 34, forming recesses, onefor each type-bar. This comb is curved to correspond to and is mountedupon the slotted type-bar-guiding plate 30, so as to move endwisethereon in any suitable manner, slots and set-screws 35 being shown.Normally the free way or unobstructed openings formed by the curvedteeth of the locking-comb coincide with the slots in thetype-bar-guiding plate, so that the typebars are free to rise to theirhighest position until they come to the bottom of the slots in theguide-plate. \Vhen the sleeve-shifting rack 23 is to be operated, ashereinafter described, the lockingcomb is caused to move endwise in thedirection of the arrow, so that its curved teeth will embrace and firmlyhold the type-bars. The sh ifting-rack 533 is then operated to bringeither face B or C of the type-bearing sleeves opposite the platen,andthen the locking-comb recedes to release the type-bars and permit theiroperation through the medium of the finger-keys, as already described.The typebearing sleeves may be frictionally or otherwise mounted uponthe type-bars, so as to yield to the stress of the shifting-rack andremain in any position into which they may be removed thereby. It ispreferred, however, to positively lock the sleeves, and this isaccomplished by providing upon the lock ing-comb 33 a series of uprightpins or studs 36, each of which engages the tail or extension 26 of alocking-latch 24:, when the locking-comb is moved in the direction ofthe arrow to lock the type-bars. By this operation the latches arelifted out of engagement with the notches on the type-bearing sleeves,their partial rotation by the shifting-rack being permitted, and on theretrogression or reverse movement of the locking-comb the latches againengage notches on the type-bearing sleeves and lock them positively intheir new position. This is clearly shown in Fig. 1, the pins 36 andlatches 24 being omitted in other general views for the sake ofclearness of illustration.

The means by which the shifting-rack and locking-comb are operated willnow be described.

Two shifting-keys 37 38, Figs. 3 and 4, mounted and equipped withreturning-springs similarly to the finger-keys 5 6 7 and preferablylocated at the left of the keyboard, have, respectively,laterally-projecting pins or lugs 37 38, each working in the slots oftwo vertical adjacent parallel plates 39 40, rocking on pivots in or onthe bed-plate. The plate 39 has a horizontal slot 39, opening at itsends into downwardly-extending slots 39 39 diverging throughout thegreater part of their length at a suitable angle from a vertical linepassing through the pivot of the plate when in the normal position andat their lower ends converging slightly. The plate 40 has also threeslots, a horizontal one, 40, somewhat longer than the slot 39, openingat its ends into down wardly-extendin g slots 40 40 The slots 40 40first incline abruptly in the same direction, (to the right, as viewedin Figs. 4, 5, and 6,) and are then throughout the greater part. oftheir length both slightly inclined in a reverse direction, thisinclination being abruptly increased near the bot tom of the slots. Thekeys are shown as arranged on opposite sides of the pair of plates, andtheir pins 37 33 project through the horizontal slots of both plates andnormally occupy the ends of the slot 39. The upper end of the plate 39is connected by a pivoted link &1 with one end of a lever 42, fulcrumedat 43 on a brace-bar 44, connecting the brackets 29 and slottedguide-plate 30. The upper end of the lever passes through a slot in thebracket 29 and is operatively connected with the endwise-movable rack23. The upper end of the plate 40 is pivotally connected to a bar 44,sliding with sufficient freedom of movement by means of a slot and screw45 on one of the side bars 46 of the frame and having alaterally-projecting pin 47 extending between the bifurcation of a lug48 on the locking-comb 33, projecting through a slot in the guide-plate30, Figs. 4 and 9. If the shifting-key 37 be depressed, the pin 37firstrides against the abruptly-inclined side of the upper part of slot 40and the bar 44 is drawn to the left, moving the locking-comb in thedirection of the arrow, causing its curved or hooked teeth to embracethe typebars and its lugs 36 to lift the latches 24 out of engagementwith the type-carrying sleeves. In its further descent the pin 37' doesnot produce any further movement of the plate 40, because the centralpart of the slot 40 is now vertical, but'it acts upon the inner edge ofthe inclined slot 39 and rocks the plate 39 to the right, thus causingthe rack 23 tomove endwise and partially rotate the type-sleeves tobring one of its side type-bearing surfaces opposite the platen. In thefurther movement of the pin 37 it runs in the now vertical lower part ofthe slot 39 the plate 39 remaining therefore stationary, and in the ab:ruptly-inclined lower part of slot 40 thereby producing a reverse orretrograde movement of the locking-comb, which releases the type-barsand permits their latches to again engage the type-carrying sleeves andlock them in their new position. The type-bars may now, while theshifting-key 37 is held down, be operated, as already described, by thefinger-keys 5 6 7. When the key 37 is released, the parts return tonormal position. On the depression of the shifting-key 38 the sameoperation of the locking-comb occurs, but the rack now moves in anopposite direction, thus bringing opposite the platen the third orremaining type-bearing faces of the sleeves. A spring 49, Fig. 9, may beapplied to the bar 44, that operates the locking-comb and tends toreturn the lockingcomb to its normal position. On each typebar adjacentto the type-bearing sleeve is a centering or truing pin 50, which enterseither one of three guide-sockets in a block51, arranged adjacent to theplaten 52, Figs. 1 and 10.

Figs. 15 and 16 show a slight modification of the latch for locking thetype -bearing sleeve. The latch 24 is straight and rocks in a singleplane parallel with the axis of the sleeve and is operated on by theinclined face 36 of a stud carried by the locking-plate 33.

Figs. 13 and 14 show another modification. Here the plate 25 at the endof the sleeve is provided with three apertures 25, whose axes areparallel with the axis of the sleeve. A locking-pin 25 sliding endwisein a bearing on the type-bar, has an angular end 25 working in aninclined slot in a lever 25 A lug or projection on the locking-comb 33operates the lever to withdraw the pin from one of the apertures, whilea coil-spring returns the lever and locking-pin to the normal positionwhen the locking comb 33 recedes. The screw that forms the pivot of thelever may also, as shown, be the centering or truing pin 50.

The platen or cylinder 52 is mounted in standards near the ends of thecarriage 53. The carriage may slide in seats or Ways in two lines ofposts 54, mounted on the bedplate and be held thereon by strips orplates 55. Any suitable arrangement or style of platen andplaten-carriage and means for actuating them may be adopted. Postsprojecting from the bottom of the carriage carry theratchet-plate 56.Any suitable arrangement of spring or weight tends to propel thecarriage from right to left of the machine, as usual, none being shownin the drawings.

57 is the feed latch or pawl device engaging the ratchet-plate. As shownin Fig. 1, the latch rocks on trunnions 57 having bearings in adjacentposts 54 of the inner row or series of such posts, and at its front end5'7 is pivotally connected to a short link 58, pivoted to a bar 58, thatconnects the rear ends of the side bars 59 of the universal bar 20. At asuitable point between their ends these side bars are connected by arock-shaft 60, having bearings in posts 61, located at ornear the sidesof the machine. Springs 62 (shown as coiled around the rock-shaft andhaving their free ends bearing, respectively, against the posts 61 andside bars 59) tend to hold the universal bar 20 against the bars 13 ofthe type-bar-actuating devices and throw down the rear ends of the sidebars.

In Fig. 1 we have merely indicated at X a rocking ribbon-carrier. Anysuitable ribboncarrier and ribbon-feed mechanism may be employed, andthe invention is in no way dependent upon or particularly related to theribbon mechanism indicated.

The form in which the accompanyingdrawings show our invention embodiedhas now been described in detail. It is plain, however, that variationsthereof may be made in its different parts without departing from theinvention or principles of construction and operation. No attempt willbe made to point out modifications in the construction 'described,except that it is deemed expedient to refer to the movable plate 1. Ofcourse with some special means for limiting the rise of the keys 5 and7such, for instance, as is shown in connection with 6the upper wall ofthe slot 2 may be removed, the primary purpose of the specialarrangement of the slots being that the lugs 5 and 7 shall act as stopsfor the plate and that between the lugs there shall be a slot, passage,or free way for the accommodation of the inactive lug during themovement of the plate. It is also plain that the slots 3 and 4 might bediverged throughout their length or not convergent at their lower parts,they being then of such length and the pins 5 7 so related to them thaton the complete depression of the key the pivot of the type-bar will bebrought to the proper position and the type just out of contact with theplaten. The usual quick impulse given to the key would impart suchmotion to the type-bar that the momentum of the end of the bar to whichit would naturally yield would be sufficient to bring the type againstthe platen with a sharp impact.

The combination of a platen, pivoted type -bars having rotatabletype -bearing sleeves, each with three type-bearing faces, each of whichhas three type longitudinally arranged thereon and one of which faces isnormally opposite the platen, mechanism for partially rotatingthesleeves in either direction to bring their other faces opposite theplaten, devices for locking the type-bars during the operation of saidmechanism, means for first throwing the locking devices into operation,then operating the sleeve-rotating mechanism and finally throwing thelocking devices out of operation, and keys three for each type-bar foroperating the type-bars when either of the faces of the sleeves isopposite the platen, one of which keys merely swings the type-bar aboutits pivot, another swings it about its pivot and advances its pivottoward the platen, and the third swings the type-bar about its pivot andmoves its pivot away from the platen.

18. The combination of the type-barshaving rotating type-bearing sleeveswith multiple type-bearing faces, and teeth or projections, anendwise-movable shifting-rack with which said teeth on the sleevenormally engage, the slotted guiding-plates 30, with one slot for eachtype-bar, the endwise-movable locking-comb having locking hooks orteeth, one for each type-bar and means for throwing the locking-combinto engagement with the type-bars, then operating the rack to partiallyrotate the sleeves and finally throwing the locking-comb out ofengagement with the type-bars.

19. The combination of the type-bars having rotating type-bearingsleeves with multiple type-bearing faces and teeth or projections, alatch for locking each sleeve in any position to which it may beadjusted, an endwise-movable shifting-rack with which said teeth on thesleeve normally engage, the slotted guide-plate 30 with one slot foreach typebar, the endwise-movable locking-comb having locking hooks orteeth, one for each typebar, and also latch-tripping lugs, one for eachlatch, and means for throwing the lockingcomb into action to lock thetype-bars and trip the latches, then operating the rack to partiallyrotate the sleeves, and finally throwin g the locking-comb out ofengagement with the type-bars and causing the reengagement of thelocking-latches with the type-bearing sleeves.

20.: The combination of the type-sleeveshifting rack, alaterally-movable plate having an inclined slot 39 therein, leverconnections between the plate and rack, and a shifting-key having a lugthat travels in said slot when the key is depressed, substantially asset forth.

21. The combination of the type-sleeveshifting rack, a laterally-movableplate having two inclined divergent slots therein, lever connectionsbetween the plate and rack, a shifting-keyhaving a lug that travels inone of said slots when the key is depressed, and a second shifting-keyhaving alugthat travels in the other of said slots when its key isdepressed,whereby on the depression of one key the rack is moved from anormal position endwise in one direction and on the depression of theother key the rack is moved endwise from the normal position in thereverse direction, substantially as set forth.

22. The combination of the endwise-movable type-bar-locking comb, alaterally-movable plate having the irregularly-shaped slot 40 therein,lever connections between the plate and locking-comb, and a key having alug that travels in said slot when the key is depressed,whereby when thekey is depressed the locking-comb is moved endwise, then re mains atrest and is finally moved endwise in a reverse direction,substantiallyas set forth.

23. The combination of the type-sleeveshiftingrack, the locking-comb,the laterallymovable plate having inclined divergent slots 39 39 thelaterally-movable plate having similar irregularlyshaped slots 40 40 ashifting-key having a lug which when the key is depressed travels in theslots 39 and 40 and a second key having a lug which when the key isdepressed travels in the slots 89 and 40 whereby on the depression ofthe first-named key the locking-comb is thro wn into operation, theshifting-rack then operated in one direction and finally thelocking-comb withdrawn to its normal position, and when the second keyis depressed the same operation occurs except that the shifting-rack isoperated in the reverse direction.

In testimony whereof we have hereunto subscribed our names.
